UPDATE
Issued at 913 PM EDT Fri May 3 2024
Main updates were to refine rain chances through the overnight hours and into early parts of Saturday morning. Upper level shortwave pivots through in the overnight hours and with upstream activity still continuing and some weak low-level convergence this evening along a frontal boundary, I have upped rain chances slightly for the overnight hours. Much of the activity the next few hours will be across southeast AL as the shortwave pivots through, with lighter showers elsewhere. This activity slides east overnight and then more activity develops closer to daybreak across the I-75 corridor and into the eastern Big Bend as the upper level forcing and weak frontal boundary help spur new development.
NEAR TERM
(Through Saturday)
Issued at 248 PM EDT Fri May 3 2024
Vapor imagery this afternoon depicts a storm system attendant to its shortwave trough traversing eastward across the Lower MS Valley with a downstream ridge axis bisecting the Coastal Carolinas down to the FL Peninsula. These features are making for warm/moist conditions with a mix of cloudiness, and isolated showers & thunderstorms today. The latter is seabreeze driven, initially focused mostly along the Eastern FL Big Bend before drifting towards the I-75 corridor into the early evening hrs. Additional cell development is possible from remnant outflow boundaries during that time.
Lingering showers are possible tonight from the west as the aforementioned shortwave pivots NE through the Wiregrass. A muggy airmass will make for an unseasonably warm overnight/early-morning period with widespread forecast lows in the upper 60s, or about 10- 12 degrees above normal! Patchy fog is also forecast to develop in the pre-dawn hrs from Southern AL/Emerald Coast, then spreading to the FL Big Bend into parts of South-Central GA. Dissipation should occur within a couple hrs after sunrise.
For tomorrow, expect greater coverage of showers and thunderstorms thanks to some upper-level support provided by the lifting shortwave, afternoon seabreeze, and sufficient daytime instability amidst a moist airmass. These parameters should support deep convection capable of strong/gusty winds, frequent lightning, and locally heavy downpours. The latter could produce localized high rain amounts exceeding 1 inch. Minimal vertical wind shear precludes severe weather concerns, but several strong storms (perhaps isolated "pulse" severe) are likely. The best chances are along the interstate corridors, followed by a northward drift past the FL state line. Aside from storm activity, temperatures peak in the mid/upper 80s.
SHORT TERM
(Saturday night through Sunday night)
Issued at 248 PM EDT Fri May 3 2024
Another shortwave will move across the mid-South Sunday into Sunday evening, which will bring another enhancement to our chances for showers and storms Sunday afternoon. The highest rain chances will be across southwest GA and the eastern FL Big Bend.
Some mid-level dry air as well as inverted-V profiles on forecast soundings may lead to some gusty wind potential Sunday afternoon.
Otherwise, it will continue to be warm and humid with highs in the upper 80s and lows in the mid to upper 60s.
LONG TERM
(Monday through Thursday)
Issued at 248 PM EDT Fri May 3 2024
One more shortwave traverses the Tennessee and Ohio Valleys Monday afternoon, which provides another boost to our rain chances.
However, forecast soundings don't appear as conducive for gusty winds given less mid-level dry air and more moisture near the surface. Highs Monday will be in the upper 80s with lows in the mid to upper 60s.
Beyond Monday, strong ridging takes hold of the area, shutting off the rain and bringing increasing heat through the middle to latter part of the week. Ensemble guidance indicates that we may see 500 mb heights near 589-590 dam, which is close to record heights for this time of year based on SPC's sounding climatology.
Similarly, 850 mb temperatures will be in the 18-22C range, which is also near record levels for this time of year. All that to say, it's going to be hot. Highs will climb in to the lower to middle 90s, and with dew points near 70, heat index values could approach 100 in some areas. Lows will also climb into the upper 60s to lower 70s.
AVIATION
(06Z TAFS)
Issued at 133 AM EDT Sat May 4 2024
Fog and/or low stratus will be possible across most of the area this morning with light showers also possible across the northern sites. Conditions should improve to VFR by mid to late morning.
Scattered to widespread showers and storms are expected this afternoon, with the best chances across TLH/ABY/VLD.

Issued at 351 AM EDT Fri May 3 2024
High pressure in the Atlantic will lead to tranquil boating conditions through the period. Light winds, generally out of the south-southeast, are expected with seas around 1 to 3 feet into the weekend. There is a slight chance of showers and thunderstorms Saturday and Sunday.
FIRE WEATHER
Issued at 248 PM EDT Fri May 3 2024
Afternoon and early evening thunderstorms capable of gusty/erratic winds and lightning will be the main fire concerns the next 3 days.
For tomorrow, convection aims to focus along the interstate corridors after seabreeze initiation on the Big Bend side, then drifting north past the FL state line. Convective potential is expected to be greater compared to today. Wetting rains are also possible. Additional rounds of diurnal showers/thunderstorms are forecast Sunday-Monday, albeit lesser coverage, but targeting roughly the same locations as Saturday. Otherwise, look for hot daytime conditions with highs in the upper 80s away from the immediate coast, southerly winds, and a daily afternoon seabreeze.
High dispersions are forecast over parts of SE AL/FL Panhandle Monday afternoon.
HYDROLOGY
Issued at 248 PM EDT Fri May 3 2024
Abundant moisture will be in place with a decent coverage of showers and storms this weekend. While widespread totals of 0.5 to 1 inch, localized totals if storms are slow moving could reach 2 to 3 inches in a short period of time. This could result in some nuisance flooding of poor drainage or urban areas. Otherwise, no additional flood concerns are expected.
